I am spawning a rabbitMQ container with the command -
docker run -d --hostname localhost --name rabbit-tox rabbitmq:3
and this is the docker ps -a output -

I am trying to connect to the container using the code -
#!/usr/bin/env python
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('127.0.0.1'))
channel = connection.channel()
channel.queue_declare(queue='hello')
channel.basic_publish(exchange='',
routing_key='hello',
body='Hello World!')
print(" [x] Sent 'Hello World!'")
connection.close()
but it gives out the error -
Traceback (most recent call last):
File "rmqtest.py", line 4, in <module>
connection = pika.BlockingConnection(pika.ConnectionParameters('127.0.0.1'))

Sorry, I am new to rabbitMQ, any help would be appreciated.
Thanks.
There are two problems I can see directly...
- No username/password
- No port forwarding.
This is Dockerfile
FROM rabbitmq:management
# Define environment variables.
ENV RABBITMQ_DEFAULT_USER user
ENV RABBITMQ_DEFAULT_PASS password
ADD init.sh /init.sh
RUN ["chmod", "+x", "/init.sh"]
EXPOSE 15672
# Define default command
CMD ["/init.sh"]
This is init.sh
#!/bin/sh
# Create Rabbitmq user
( sleep 10 ; \
rabbitmqctl add_user user password ; \
rabbitmqctl set_user_tags user administrator ; \
rabbitmqctl set_permissions -p / user ".*" ".*" ".*" ; \
echo "*** User 'user' with password 'password' completed. ***" ; \
echo "*** Log in the WebUI at port 15672 (example: http:/localhost:15672) ***") &
# $@ is used to pass arguments to the rabbitmq-server command.
# For example if you use it like this: docker run -d rabbitmq arg1 arg2,
# it will be as you run in the container rabbitmq-server arg1 arg2
rabbitmq-server $@
Put the Dockerfile and the init.sh in one folder and then do: docker build -t 'my_rabbit' . - This will build your image.
Then do docker run -p5672:5672 -p15672:15672 my_rabbit
5672 - This is the port RabbitMQ sends it's messages on.
15672 - This is the port RabbitMQ's management GUI.
If you are running this on your localmachine, you can navigate to: localhost:15672 and enter username: user and password: password and voila. It should all work just fine!
